在Cygwin上使用Ant创建RPM

标签: ant cygwin rpm rpmbuild

所以我有一个基本的Java程序,我试图使用Ant的rpm任务打包为RPM。我是通过Cygwin运行的。我的问题是当我运行ant build脚本时,它似乎试图使用rpm命令而不是所需的rpmbuild命令。根据我的阅读,ant rpm任务应该使用rpmbuild,除非找不到,在这种情况下它使用rpm。我知道两者都安装正确,因为我可以使用命令行手动创建RPM。我不确定在构建脚本或spec文件中是否需要更改以使其正常工作,因为我是这类新手。或者,如果这是一个Cygwin依赖问题?

Cygwin中的rpm和rpmbuild安装证明:

$ which rpm
/usr/bin/rpm

$ which rpmbuild
/usr/bin/rpmbuild

这是我的build.xml文件:

<project name="SimpleJavaApp" default="all">

<property name="src"        value="${basedir}/src" />
<property name="output"     value="${basedir}/output" />
<property name="classes"    value="${output}/classes" />
<property name="jars"       value="${output}/jars" />
<property name="build.dir"  value="${basedir}/build"/>

<target name="clean">
    <delete dir="${output}" />
</target>

<target name="compile">
    <mkdir dir="${classes}" />
    <javac srcdir="${src}" destdir="${classes}" />
</target>

<target name="jar">
    <mkdir dir="${jars}" />
    <jar basedir="${classes}" destfile="${jars}/app.jar">
        <manifest>
              <attribute name="Main-Class" value="Main"/>
        </manifest>
    </jar>
</target>

<!-- Create directories -->
<mkdir dir="${build.dir}/BUILD"/>
<mkdir dir="${build.dir}/SOURCES"/>
<mkdir dir="${build.dir}/RPMS/noarch"/>
<mkdir dir="${build.dir}/SPECS"/>

<!-- copy spec files -->
<copy todir="${build.dir}/SPECS" preservelastmodified="true" failonerror="true">
    <fileset dir="${basedir}" includes="*.spec"/>
</copy>

<target name="rpm" description="Compile single binary rpm by spec file">
    <rpm
        specFile="project.spec"
        topDir="build"
        cleanBuildDir="false"
        removeSpec="false"
        removeSource="false"
        command = "ba"
        failOnError="false"
    />
</target>


<target name="all" depends="clean, compile, jar, rpm" />

这是我的spec文件,非常简单:

Summary:    An RPM Spec example
Name:       Application-Example
Version:    1.0
Release:    1
Group:  Applications/Sample
URL:        http://www.mycompany.com
Packager:   Name <name@name.com>
BuildArch:  noarch

%description
This is a sample SPEC file for the RPM project
demonstrating how to build, package, install(deploy)

%files

最后,这是ant build的输出(只有rpm部分):

如果您想了解ant run中发生的事情,您应该了解您感兴趣的任务的来源。不确定您拥有的ant版本,但最新的来源可以在这里看到:{{3 }}

您感兴趣的方法似乎是:

 /**
 * Checks whether <code>rpmbuild</code> is on the PATH and returns
 * the absolute path to it - falls back to <code>rpm</code>
 * otherwise.
 *
 * @return the command used to build RPM's
 *
 * @since 1.6
 */
protected String guessRpmBuildCommand() {
    Map/*<String, String>*/ env = Execute.getEnvironmentVariables();
    String path = (String) env.get(PATH1);
    if (path == null) {
        path = (String) env.get(PATH2);
        if (path == null) {
            path = (String) env.get(PATH3);
        }
    }

    if (path != null) {
        Path p = new Path(getProject(), path);
        String[] pElements = p.list();
        for (int i = 0; i < pElements.length; i++) {
            File f = new File(pElements[i],
                              "rpmbuild"
                              + (Os.isFamily("dos") ? ".exe" : ""));
            if (f.canRead()) {
                return f.getAbsolutePath();
            }
        }
    }

    return "rpm";
}

参考的常数是:

private static final String PATH1 = "PATH";
private static final String PATH2 = "Path";
private static final String PATH3 = "path";

正如您所提到的,它基本上只是试图在您的路径上找到rpmbuild。如果找不到它,则会转到rpm

问题是,我没有安装cygwin(因为我是linux用户),但是让我提议,我会尝试一下。

  1. 尝试使用-verbose选项运行ant(如此处所示:http://svn.apache.org/viewvc/ant/core/trunk/src/main/org/apache/tools/ant/taskdefs/optional/Rpm.java?view=markup)并查看它是否告诉您有用的内容
  2. 如果没有,请尝试下载ant源(您使用的版本),将它们导入您喜欢的java ide并进行远程调试以查看发生了什么。我在第333行附近设置了断点,看看是否找到了rpmbuild。如果您不确定如何为ant设置远程调试,请参阅:http://ant.apache.org/problems.html
  3. 我不知道cygwin中可执行文件的外观,但问题是它们是否有.exe扩展名。另一个重要的问题是如果Os.isFamily("dos")在cygwin中被评估为真。

    玩得开心:)
